Cow's Milk: A Benefit for Human Health? Omics Tools and Precision Nutrition for Lactose Intolerance Management.

Cow's milk (CM) is a healthy food consumed worldwide by individuals of all ages. Unfortunately, "lactase-deficient" individuals cannot digest milk's main carbohydrate, lactose, depriving themselves of highly beneficial milk proteins like casein, lactoalbumin, and lactoglobulin due to lactose intolerance (LI), while other individuals develop allergies specifically against these proteins (CMPA). The management of these conditions differs, and an inappropriate diagnosis or treatment may have significant implications for the patients, especially if they are infants or very young children, resulting in unnecessary dietary restrictions or avoidable adverse reactions. Omics technologies play a pivotal role in elucidating the intricate interactions between nutrients and the human body, spanning from genetic factors to the microbiota profile and metabolites. This comprehensive approach enables the precise delineation and identification of distinct cohorts of individuals with specific dietary requirements, so that tailored nutrition strategies can be developed. This is what is called personalized nutrition or precision nutrition (PN), the area of nutrition that focuses on the effects of nutrients on the genome, proteome, and metabolome, promoting well-being and health, preventing diseases, reducing chronic disease incidence, and increasing life expectancy. Here, we report the opinion of the scientific community proposing to replace the "one size fits all" approach with tailor-made nutrition programs, designed by integrating nutrigenomic data together with clinical parameters and microbiota profiles, taking into account the individual lactose tolerance threshold and needs in terms of specific nutrients intake. This customized approach could help LI patients to improve their quality of life, overcoming depression or anxiety often resulting from the individual perception of this condition as different from a normal state.

Myths and Facts about Food Intolerance: A Narrative Review

Most adverse reactions to food are patient self-reported and not based on validated tests but nevertheless lead to dietary restrictions, with patients believing that these restrictions will improve their symptoms and quality of life. We aimed to clarify the myths and reality of common food intolerances, giving clinicians a guide on diagnosing and treating these cases. We performed a narrative review of the latest evidence on the widespread food intolerances reported by our patients, giving indications on the clinical presentations, possible tests, and dietary suggestions, and underlining the myths and reality. While lactose intolerance and hereditary fructose intolerance are based on well-defined mechanisms and have validated diagnostic tests, non-coeliac gluten sensitivity and fermentable oligosaccharide, disaccharide, monosaccharide, and polyol (FODMAP) intolerance are mainly based on patients’ reports. Others, like non-hereditary fructose, sorbitol, and histamine intolerance, still need more evidence and often cause unnecessary dietary restrictions. Finally, the main outcome of the present review is that the medical community should work to reduce the spread of unvalidated tests, the leading cause of the problematic management of our patients.

The role of online symptom questionnaires to support the diagnosis of cow's milk allergy in children for healthcare professionals - A Delphi consensus study.

Cow's milk allergy (CMA) is one of the most common food allergies world-wide. The emergence of online CMA symptom questionnaires, aimed at parents and/or healthcare professionals (HCP), may raise awareness about the possible diagnosis of CMA, but also increases the risk for overdiagnosis leading to unnecessary dietary restriction impacting on growth and nutrition. This publication sets out to establish the availability of these CMA symptom questionnaires and critically assesses the development and validity. Thirteen HCP working in the field of CMA, from different countries, were recruited to participate. A combination of a Pubmed and CINAHL literature and online review using the Google search engine in English language was used. Symptoms in the questionnaires were assessed, using the European Academy for Allergy and Clinical Immunology guidelines for food allergy. Following the assessment of both the questionnaires and literature, the authors followed the modified Delphi approach to generate consensus statements. Six hundred and fifty-one publications were identified, of which 29 were suitable for inclusion, with 26 being associated with the Cow's Milk-Related Symptoms Score. The online search yielded 10 available questionnaires: 7/10 were sponsored by formula milk companies and 7/10 were aimed at parents and three at HCP. Following the assessment of data, 19 statements were generated in two rounds of anonymous voting reaching 100% agreement. Online CMA questionnaires, available to parents and HCP's, are varied in symptoms, and most were not validated. The overarching consensus generated from authors is that these questionnaires should not be used without the involvement of HCP.

IgE-mediated fish allergy in Singaporean children.

Fish is one of the common causes of food allergy and there is limited literature about fish allergy in Singapore. We aimed to describe the demographics, clinical features, and natural history of children with IgE-mediated fish allergy. A retrospective review was conducted for children diagnosed with fish allergy in a tertiary pediatric hospital in Singapore between 2015 and 2020. The diagnosis of fish allergy was made in 108 patients based on a convincing history of IgE-mediated allergic reaction and a positive skin prick test. The median age at first reaction was 12 months (range 6-168) with most reacting on first ingestion (62.0%). The most common fish causing reactions were threadfin (48.1%), salmon (33.3%) and cod (31.5%). Majority presented with cutaneous symptoms (97.2%). Anaphylaxis occurred in 6.5%. Five were mono-sensitized (4.6%), 77 were oligo-sensitized (71.3%) and 26 were polysensitized (24.1%). Most can tolerate another species of fish (75.9%), most commonly salmon (37.0%), tuna (24.1%) and cod (22.2%). Median duration of follow up was 24 months (range 0-176). Twenty-eight out of 108 children (25.9%) acquired natural tolerance to index fish at a median age of 60 months (range 18-159). Most children with fish allergy can tolerate at least one other species of fish and resolution of fish allergy is possible. Thus, it is important to follow-up with an allergist to evaluate which fish species can be included in their diet to avoid unnecessary dietary restrictions.

Clinical Management of Seafood Allergy

Seafood plays an important role in human nutrition and health. A good patient workup and sensitive diagnostic analysis of IgE antibody reactivity can distinguish between a true seafood allergy and other adverse reactions generated by toxins or parasites contaminating ingested seafood. The 2 most important seafood groupings include the fish and shellfish. Shellfish, in the context of seafood consumption, constitutes a diverse group of species subdivided into crustaceans and mollusks. The prevalence of shellfish allergy seems to be higher than that of fish allergy, with an estimate of up to 3% in the adult population and fin fish allergy prevalence of approximately 1%. Clinical evaluation of the seafood-allergic patient involves obtaining a detailed history and obtaining invivo and/or invitro testing with careful interpretation of results with consideration of cross-reactivity features of the major allergens. Oral food challenge is useful not only for the diagnosis but also for avoiding unnecessary dietary restrictions. In this review, we highlight some of the recent reports to provide solid clinical and laboratory tools for the differentiation of fish allergy from shellfish allergy, enabling best treatment and management of these patients.

Roles of Lactose and Fructose Malabsorption and Dietary Outcomes in Children Presenting with Chronic Abdominal Pain

Intolerance to lactose or fructose is frequently diagnosed in children with chronic abdominal pain (CAP). However, the causal relationship remains a matter of discussion. A cohort of 253 patients, aged 7–12 years, presenting with unexplained CAP received standardized diagnostics. Additional diagnostic tests were performed based on their medical history and physical and laboratory investigations. Fructose and lactose hydrogen breath tests (H2BT) as well as empiric diagnostic elimination diets were performed in 135 patients reporting abdominal pain related to the consumption of lactose or fructose to evaluate carbohydrate intolerance as a potential cause of CAP. Carbohydrate malabsorption by H2BT was found in 55 (41%) out of 135 patients. An abnormal increase in H2BT was revealed in 30% (35/118) of patients after fructose consumption and in 18% (20/114) of patients after lactose administration. Forty-six percent (25/54) reported pain relief during a diagnostic elimination diet. In total, 17 patients had lactose malabsorption, 29 fructose malabsorption, and nine combined carbohydrate malabsorption. Carbohydrate intolerance as a cause of CAP was diagnosed at follow-up in only 18% (10/55) of patients with malabsorption after the elimination of the respective carbohydrate. Thus, carbohydrate malabsorption appears to be an incidental finding in children with functional abdominal pain disorders, rather than its cause. Therefore, testing of carbohydrate intolerance should only be considered in children with a strong clinical suspicion and with the goal to prevent long-term unnecessary dietary restrictions in children suffering from CAP.

Parental understanding of relapsing idiopathic nephrotic syndrome-Where are the knowledge gaps?

To assess parental understanding of idiopathic nephrotic syndrome (INS) and its management, to enable targeted education in areas of deficit. Families of children with at least one relapse of INS were interviewed, following a template covering key domains of (a) disease understanding, (b) management of INS and (c) access to information. Common trends and responses were identified and notable observations recorded. Twenty-one parents were interviewed. The mean duration of INS was 4.4years (range 0.5-14.5years), with a mean of two steroid-sparing agents used. Although 90% parents self-reported that they understood INS, only 29% could appropriately define relapse and 24% name potential complications. The management of INS was generally good, with most parents appropriately testing urine (81%) and managing relapses (90%). Unnecessary dietary restrictions were imposed on 57% during remission. The Internet was searched by 90% of parents for disease and drug information. Further information was desired in paper form (71%), hospital website (81%) and face-to-face workshop (90%), plus educational materials for schools. Parents overestimated their understanding of INS; however, their management was generally well done. Parents desired more information and support in various forms.

Testing the Cow's Milk-Related Symptom Score (CoMiSSTM) for the Response to a Cow's Milk-Free Diet in Infants: A Prospective Study.

The diagnosis of cow’s milk allergy (CMA) is particularly challenging in infants, especially with non-Immunoglobulin E (IgE)-mediated manifestations, and inaccurate diagnosis may lead to unnecessary dietary restrictions. The aim of this study was to assess the accuracy of the cow’s milk-related symptom score (CoMiSSTM) in response to a cow’s milk-free diet (CMFD). We prospectively recruited 47 infants (median age three months) who had been placed on a CMFD due to persisting unexplained gastrointestinal symptoms. We compared data with 94 healthy controls (median age three months). The CoMiSSTM score was completed at recruitment and while on the exclusion diet. In 19/47 (40%) cases a response to the diet occurred. At recruitment CoMiSSTM was significantly higher in cases compared to controls (median score 8 vs. 3; p-value: <0.05), 9 cases had a score ≥12 and 8/9 normalized on CMFD. An oral milk challenge was performed in all 19 responders and six of these had a positive reaction to cow’s milk (CM). In eight infants IgE allergy tests were positive. The receiver operation characteristic (ROC) curve identified a CoMISSTM score of 9 to be the best cut-off value (84% sensitivity, 85% specificity, 80% positive (PPV) and 88% negative predictive value (NPV)) for the response to CMFD. We found CoMiSSTM to be a useful tool to help identify infants with persisting gastrointestinal symptoms and suspected CMA that would benefit from CMFD.

Self-Prescribed Dietary Restrictions are Common in Inflammatory Bowel Disease Patients and Are Associated with Low Bone Mineralization.

Background and objectives: Despite the serious concerns of patients about the role of food in triggering or ameliorating their intestinal disease, there are few studies dealing with patients’ beliefs and practices regarding diet in inflammatory bowel disease (IBD). The aim of this study was to investigate how the disease affected the dietary habits of patients with IBD, and to assess if patients’ food restrictions were responsible for low bone mineralization. Materials and Methods: For this study, 90 consecutive patients referred for IBD were interviewed regarding their dietary habits. Demographic features and clinical characteristics potentially associated with the dietary habits were collected. A validated and self-administered survey questionnaire dealing with dietary habits and patients’ beliefs and perceptions regarding food was analyzed. Multivariate logistic regression analysis was performed in order to identify risk factors for dietary restrictions among participants and to evaluate the relationship between dietary restrictions and low bone mineral density (BMD). Results: Among the 63 (70%) patients who claimed a self-prescribed dietary restriction, 84% avoided dairy products. Significant risk factors (adjusted odds ratio (OR), 95% confidence interval (CI)) for the dietary restrictions were a younger age (p = 0.02), a higher level of education (p = 0.007), and a higher visceral sensitivity index (p = 0.009). Most (80%) of the patients displayed an inadequate calcium intake, and an abnormal result at dual-energy X-ray absorptiometry (DXA) scan accounting for low BMD was reported in 46 (51%) of them. Dietary restrictions (p = 0.03), and in particular avoiding dairy products (p = 0.001), were significant risk factors for a low BMD, along with female gender (p = 0.001), smoking (p = 0.04), and steroid abuse (p = 0.03). Almost all (86%) patients changed their diet after IBD diagnosis, as 8% believed that foods could have been a trigger for IBD and 37% that a proper diet was more important than drugs in controlling disease. Although 61% of the patients claimed to have received nutritional advice, 78% of the participants showed interest in receiving more. Conclusions: Dietary habits of IBD patients should be investigated by healthcare professionals as part of the routine visit. Clinicians are invited to provide nutritional recommendations to these patients in order to avoid unnecessary self-prescribed dietary restrictions.

Nefrolitiaziste Tıbbi Beslenme Tedavisi

Dünya çapında nefrolitiazisin prevalansı ve insidansının giderek arttığı bildirilmektedir. Son yıllarda nefrolitiazis alanında önemli ilerlemeler kaydedilmiştir. Taş oluşum nedenleri ve spesifik moleküler defektler daha kapsamlı olarak ortaya konulmaktadır. İdrar yoğunluğunun yanında idrarda çözünen kristallerin miktarı da böbrek taşı oluşumunda etkilidir. İdrar hacminin azalmasıyla birlikte idrardaki çözünen maddelerin saturasyanu değişir ve taş oluşum riski artar. İdrarda okzalat ve fosfor gibi bazı maddelerin yüksek düzeyi ile böbrek taşları oluşabilmektedir. Genler, metabolik ve çevresel etmenler idrar bileşimini etkileyebilmekte ve taş oluşum riskini arttırabilmektedir. Diyet de böbrek taş oluşumuna neden olabilen ya da taş oluşumunu önleyebilen bir etmendir. Diyet uygulamasındaki değişiklikler ise böbrek taşlarının tedavisinde ve önlenmesinde anahtar bir rol oynayabilmektedir. Böbrek taşlarının ortaya çıkışının ya da yenilenmesinin önlenmesinde idrar süper saturasyonunun azaltılması önemlidir. Bu yüzden idrar hacmi 2-2.5 litre olana kadar sıvı alımının arttırılması hedeflenmelidir. Diyetteki okzalat miktarı arttığında veya kalsiyum düşük olduğunda ortaya çıkabilen hiperoksalüri, kalsiyum okzalat taşı oluşumu için risk etmenidir. Gereksiz diyetsel kalsiyum kısıtlamalarından kaçınmak ve okzalattan zengin besinleri diyette kontrol altına almak böbrek taşının önlenmesi için önemlidir. Artmış diyet sodyum alımı, kalsiyum renal tübüler geri emilimini azaltarak böbrek taşı için risk etmeni olan hiperkalsiüriyi tetikleyebileceği için, diyetle sodyum alımının düzenlemesine gidilebilmektedir. Bu yüzden böbrek taşı oluşumunu ve tekrarlamasını önleyebilmek adına çevresel etmenlerden özellikle beslenmenin de kontrol altına alınması gerekebilmektedir.

Dietary Practices Adopted by Track-and-Field Athletes: Gluten-Free, Low FODMAP, Vegetarian, and Fasting.

Some track-and-field athletes implement special diets aiming to improve health and/or performance. An evidence-based approach to any diet is recommended to minimize the risks associated with unnecessary dietary restriction, which may potentially do more harm than good. Four prevalent diets are reviewed in this study: (a)gluten-free; (b)low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP); (c)vegetarian; and (d)fasting diets. Recently, gluten-free diets and low FODMAP diets have emerged as novel regimes thought to improve gastrointestinal health and reduce the risk of exercise-associated gastrointestinal symptoms. No direct beneficial outcomes have been associated with avoiding gluten for clinically healthy athletes. Indirectly, a gluten-free diet is associated with other dietary changes, particularly FODMAP reduction, which may improve adverse gastrointestinal symptoms. Vegetarian diets can optimally support athletic demands. However, attention is required to ensure adequate energy and intake of specific nutrients that are less abundant or less well absorbed from plant sources. Finally, fasting is a long-standing concept that is undertaken on a voluntary and obligatory basis. Despite limited supporting research, voluntary fasting is a popular alternative to conventional diets perceptually offering health and body composition benefits. Strict obligatory fasting guidelines likely require the implementation of tailored nutrition strategies to help athletes cope with athletic demands. Overall, a multitude of factors influence adherence to special diets. Even when adherence to a special diet is a necessity, education and advice from an accredited dietitian/nutritionist are recommended for track-and-field athletes to optimize nutrition for health and performance.

Nutrient Recommendations for Cancer Patients Treated with Pelvic Radiotherapy, with or without Comorbidities.

Radiotherapy is one of the main treatment options used in pelvic cancers. Ionizing radiation induces damage to surrounding tissues, resulting in disruption of normal physiological functions and symptoms such as diarrhea, tenesmus, incontinence, and rectal bleeding, which can all significantly alter the patient's quality of life. These patients are at increased risk of developing protein-calorie malnutrition and micronutrient deficiencies. Therefore, designing a proper nutritional intervention plan, with an optimal proportion of protein, fat, and carbohydrates, is required to reduce or even reverse the patients' poor nutritional status, increase their tolerance and response to oncology treatment, decrease the rate of complications and improve their quality of life. The aim of this review was to establish a nutritional plan that includes recommendations on macronutrient proportions and micronutrient intake in patients receiving pelvic radiotherapy. The following nutritional plan has been recommended in the literature: Energy: 28-31 kcal/kg/day, using the Harris-Benedict formula adjusted for body weight in obese patients; protein: 20-30%; fat: 30-40%; and carbohydrates: 40-50%. The maintenance of adequate levels of Vitamin D, Vitamin E, Vitamin A, calcium, magnesium, thiamin, riboflavin, and niacin must be emphasized. Physical activity must also be increased to maintain muscle mass. Nutrient requirements must be established in an integral manner, considering the patient's age, nutritional status, and the presence of comorbidities. Unnecessary dietary restrictions should be avoided to ensure an adequate nutritional status.

Precision medicine in cow's milk allergy: proteomics perspectives from allergens to patients

Cow's milk allergy (CMA) is one of the most common food allergies, especially during childhood. CMA is an immunological mediated adverse reaction to one or more cow's milk proteins, which are normally harmless to a non-allergic individual, as the result of a failure of oral tolerance. To make a correct diagnosis of CMA and a proper treatment is critical in clinical practice. Application of proteomics along with new bio-informatics tools in the field of food allergy is one of the hot topics presented in recent years. In the present review, we focus on recent applications of proteomics to the field of cow's milk allergy, from allergens quantification to the diagnosis, treatment and prognosis. Furthermore, we also shed a light on potential future directions and developments, that are parts of personalized medicine but also of the One Health approach. SignificanceThe field of food allergies is becoming a milestone in public health. Food allergies, in fact, can cause life-threatening reactions and profoundly influence the quality of life. Precise, fast and reliable diagnosis of food allergies, and in particular milk allergies is essential to avoid severe allergic reactions and also to prevent dangerous and eventually unnecessary dietary restrictions; but this can be difficult also due to a complex interaction of genetic background, environment, and microbiota. In this sense, proteomics represents steps toward researching food and milk allergy integrated with the clinic to improve pathophysiology, diagnosis, therapy, and prognosis.

Step-up empiric elimination diet for pediatric and adult eosinophilic esophagitis: The 2-4-6 study

Numerous dietary restrictions and endoscopies limit the implementation of empiric elimination diets in patients with eosinophilic esophagitis (EoE). Milk and wheat/gluten are the most common food triggers. We sought to assess the effectiveness of a step-up dietary strategy for EoE. We performed a prospective study conducted in 14 centers. Patients underwent a 6-week 2-food-group elimination diet (TFGED; milk and gluten-containing cereals). Remission was defined by symptom improvement and less than 15 eosinophils/high-power field. Nonresponders were gradually offered a 4-food-group elimination diet (FFGED; TFGED plus egg and legumes) and a 6-food-group elimination diet (SFGED; FFGED plus nuts and fish/seafood). In responders eliminated food groups were reintroduced individually, followed by endoscopy. One hundred thirty patients (25 pediatric patients) were enrolled, with 97 completing all phases of the study. ATFGED achieved EoE remission in 56 (43%) patients, with no differences between ages. Food triggers in TFGED responders were milk (52%), gluten-containing grains (16%), and both (28%). EoE induced only by milk was present in 18% and 33% of adults and children, respectively. Remission rates with FFGEDs and SFGEDs were 60% and 79%, with increasing food triggers, especially after an SFGED. Overall, 55 (91.6%) of 60 of the TFGED/FFGED responders had 1 or 2 food triggers. Compared with the initial SFGED, a step-up strategy reduced endoscopic procedures and diagnostic process time by 20%. A TFGED diet achieves EoE remission in 43% of children and adults. Astep-up approach results in early identification of a majority of responders to an empiric diet with few food triggers, avoiding unnecessary dietary restrictions, saving endoscopies, and shortening the diagnostic process.

Special diets are common among preschool children aged one to five years in south-east Sweden according to a population-based cross-sectional survey.

Information about the prevalence of special diets in preschool children is limited. The aim of this study was to measure the prevalence of all special diets among preschool children in a Swedish municipality. This was a population-based cross-sectional survey of all 3276 preschool children aged one to five years in the municipality of Karlskrona, Sweden. The questionnaire assessed the number of children at each preschool, how many were on special diets, their dietary requirements, age, sex, whether they had a medical certificate and whether the special diet had a perceived medical cause. We obtained data for 3221 (98%) of the children, and 19% had special diets, including 12% on nonmedical diets and 6.3% on medical diets. The five most common diets were avoiding pork (7.8%), a vegetarian diet (4.8%), and avoiding cows' milk (3.5%), hens' eggs (1.2%) and lactose (1.1%). Gluten avoidance was more common in girls than boys (0.8% versus 0.2%, p = 0.032). Half (47%) of the children on special medical diets lacked a medical certificate. Special diets were common in preschool children in south-east Sweden, and the causes were mainly nonmedical. Mandatory medical certificates for medically based special diets might reduce unnecessary dietary restrictions.

Utility of component diagnostic testing in guiding oral food challenges to milk and egg.

Food allergies affect up to 8% of children, and milk and egg allergies are the most common triggers. Accurately diagnosing these food allergies is important to prevent allergic reactions and to avoid unnecessary dietary restrictions. However, positive skin-prick tests and detectable levels of serum food specific immunoglobulin E (IgE) alone may not be diagnostic for food allergy. Advances in the identification of relevant allergens and the development of recombinant proteins now allow assessment of IgE binding to individual proteins within a food. Component-resolved diagnostics (CRD) have the potential to provide more accurate assessments of clinical reactivity to food allergens. To examine the available data for CRD for milk and egg allergies. This review discussed studies that evaluated the utility of CRD for guiding decisions about food challenges for milk and egg. Results of studies indicated that CRD may offer increased specificity, but sensitivity was lacking when compared with standard skin-prick testing and measurement of serum food specific IgE levels. The role of CRD in the diagnosis and management of milk and egg allergies is not well established at this time. Further studies are needed to explore the diagnostic value of CRD for milk and egg allergies.

Differentiating milk allergy (IgE and non-IgE mediated) from lactose intolerance: understanding the underlying mechanisms and presentations.

Children with food allergy and, in particular, infants with suspected adverse reactions to cow’s milk, commonly present to primary care. It is thought that 6–8% of children aged <3 years have a food allergy1 and up to 4.9% have a cow’s milk allergy.2 Inconsistencies in the management of food allergy prompted the commissioning of projects such as the National Institute for Health and Care Excellence (NICE) clinical guideline on the diagnosis and assessment of food allergy in the community1 and in 2014 the NICE Clinical Knowledge Summary looking specifically at the management of milk allergy.3 It has been shown that GPs’ knowledge of these guidelines is poor. Inconsistencies remain in the management of milk allergy, with a particularly lengthy time period and multiple consultations before diagnosis.4 There is anecdotal evidence of confusion between lactose intolerance and milk allergy among both patients and physicians, which could result in unnecessary dietary restriction or avoidable reactions. Terminology such as suspected ‘milk allergy’, ‘milk intolerance’, and also ‘lactose intolerance’ are often used without a clear sense of the different meanings, understanding of the different mechanisms that underlie them, or the dietary implications of the diagnosis. The management of these conditions is distinctly different, and inappropriate recognition or management may have significant implications for the patient. In the last 15 years, there have been many discussions on the nomenclature of reactions to foods, including milk. The currently accepted nomenclature is …
